I'm sorry for not explaining where to find it, you have to do show application contents on the application (right/ctrl click) to do it in finder or it's in /Applications/PS3\ Media\ Server.app/Contents/Resources/Java/ which is kind of the default 'current directory' for OS X Java Apps.

I have noticed a quirk or two though. I'm not sure if it appears in other versions, as I've only tried the OSX version. When you approach the end of a tsMuxeR file, the playback becomes jittery and starts replaying old clips from earlier, rather than just ending as expected. I think it's seeking further and further back in the file (due to -ve arguments to seek_set?) buffer usage goes negative too.

Also rewind doesn't work very well in general, and fast forward is not as good as when using mencoder. The benefit of virtually 0 cpu load is well worth the loss of seek functionality tho!

OK, seek I don't mind too much, as I said it's liveable with. The bigger problem is that the buffer doesn't drain properly at the end of the program when coming to the end and so you miss the last seconds of the program and playback doesnt stop at the end. I managed to confirm DTS working today. The PS3 thought it was playing a Stereo PCM source at 1.5Mbit but the amp recognised it as DTS. Very impressive.

I'm sure it's a relatively simple fix (compared to the work done so far!)

Oh wow, that latest beta build is absolutely superb! Thank you so much! It is interesting how it reads 2CH LPCM on the display but it seems as though it forces the PS3 to bitstream the DTS stream to my receiver. I have my PS3 set to LPCM since I have a HDMI receiver so typically the PS3 handles the decoding but this works flawlessly.
